M ECHANICAL GLASS-BLOWER.

SPECIFICATION forming part of Letters Patent No. 360,552I dated April 5, 1887.

Application filed July 15, 1886. Serial No. 208,137. (No model.)

To aZZ whom it may concern.:

Be it known that I, WILMo'r G. BAILEY, of Burgettstown, Washington county, Pennsyl- Vania, have invented a new and useful Im provement in Mechanical Glass-Blowers, which improvement is fully set forth in the following specification, reference being had to the accompanying drawings.

Similar letters of reference indicate corresponding parts.

My invention relates to a device for employing compressed air, together with adequate machinery, to perform the operation of blowing windowglass-a work now done by the operator employing air from his lungs through a blow-pipe, which he turns and swings to and fro while performing the operation.

In the accompanying drawings, Figure l is a side elevation of my device. Fig. 2 is a horizontal section of the lower part of Fig. l. Fig. 3 is a top View of the upper part of Fig. l. Fig. 4 is a vertical section of a clamp used at e to hold the blow-pipe. Fig. 5 is a perspective View of a building with my glassblowing machinery in posit-ion for operation; and Fig. 6 is avertical section and full length of the parts A and A2.

A, A, A, and A3 are in one piece, and in the form of a cross. The parts A and A2 are hollow, for airpassages, while the part A3 is ho1low,for a valve-rod, and the part A is solid.

B is a blow-furnace with door bi". B2 is a rack for glass cylinders to rest on after being blown.

B3 is a glass-furnace with pot-holes b b.

B4 is the shapening-block, hollow or concave on top for holding water, for a wellknown purpose.

b is a cap screwed on the end of A2, and is capable of adjustment of the journal cl on the part A2, and thus adjusting the bevel-wheel C to a proper position.

b is a gum packing between the caps b and b2. This cap b' is held tightly up against the gum packing b by the stud-bolts e?, through the slots in the arms e. (Seen iu Fig. l.)

b3 is a metal cap,which is hollow in the een ter, and has the arms b5 to secure it by bolts to the cap b.

If is a set-screw, and I use it to prevent the unserewing of the cap b, which might be done without such a fastening.

G is a large bevel-wheel fixed rigidly to the journal d, so as to revolve with it. C' is also a large bevel-wheel, fixed to a journal, c, and revolves with the part A3.

cis a weighted leveiywhich, by a cani-movement, serves to throw the wheel C into place in wheel C and also out of place, as required.

c2 is a valve on the rod ci.

cil is a small bevelwheel on the shaft c is a small pinion-wheel at the other end of the shaft c5 from the wheel o4.

CQ is a power-wheel with cogs to operate the .pinion-wheel c". This power-wheel Cl has a handle, es.

N is an iron rod fastened to a pin, u, which is used to secure the turn-table at any fixed or desired position. The pin oz. passes up into the turn-table, and is held there by the spiral spring n.

o is a lubricating-vessel.

D is a swivel-joint at the end ofthe part A, and has a packing, d.

D D are angleiron suspenders, in which the parts A and Ail rest. These irons D are fastened to the turn-table I-I. There will be two of these irons D, and made strong enough to securely bear up the weight of my ma chine.

e c are two iron arms, forming a support and guide for the blow-pipe mv. These arms e e are rigidly tixed to the journal cl by bolts at the points e e.

e is theinside of the terminus c* of the arms e e. lThis terminus of the arms will be in two sections, so as to be opened out more or less when the blow-pipe is being inserted. The ehecker-work inside of e4 is to create a friction that will prevent the pipe m from turning. To this part c", I iix a clamp, (see Fig. 4,) of which J is the upper half and J the lower half, and these two parts are hinged at j.

j is a handle to J, andj2 a handle for J.

j? is a rubber packing or spring, and j* a steel cap.

j; is a fastener of the two sections J and J', and is held fast by a spring when the upper and lower parts, as aforesaid, are brought together, to rmly hold the blow-pipe m in place.

K is a shaft ou which a balance-weight, w, is moved. x is a setscrew to hold this weight at such place asis desired. The weight w is intended as a means of balancing the glass IOO that may be on the blow-pipe, thus making it easier on the operator to manipulate my machine.

F is a large cog-wheel fixed rigidly to an angle-iron suspender, D', and serves to lock the machine at any desired angle. On the outside of this wheel F, on the part A3, I x alever, f', at f, (sec Fig. 5,) having a handle, f3. By this means a revolving movement can be given to the blow pipe as the lever f is rigidly fixed to the part A a complete cycle can be given, if necessary, in the blowing process to the glass being blown, and this revolving motion can be checked at any angle, andy there held by means of the pawl j, operated by the lever fs.

f is a handle at theend of the valverod ci. f* is a spiral spring. fl is a rod with a fulcrum attachment, f, at f5, and has a` handle, flo. By means of this handle, the rod ci and valve c are operated. As this valve is lmade concave on top and bottom the com.- pressed air will be on either side thereof, rendering the movement of the valve an easy work.

H is the turn-table, moving on the carryingwheels h h. This turn-table is placed on a car, H', and the latter moves on a track, H2 H. (See Fig. 5.) h"

H3 H3 are the outlines of a glass-house structnre.

L represents a glass cylinder blown out and still on the blowpipe m. The hose a' may be made to pass directly overhead and above the machine or blower, and there connect with an air-receiver.

A device to regulate the pressure of air, of which there are many kinds, can be used for my glassblower. The blow-pipe m has a coneshaped collar to aid in holding the pijpe in place and prevent a slipping out when the glass ball is being swung around.

Having thus referred to the several parts of my invention, I will now describe the working ot' the same. To turn the glass-blower around horizontally, the pin a' is pulled out of place, and this unlocks the turn-table H. The'operator can then turn the same at will, one way or the other, part or all the way around. In Fig. 5 the glass-blower is presented toward the blow=furnace B', but when the glass was irst manipulated the blower was presented (facing) toward the glass-furnace B3, and this turn was effected, as above described. When glass has been gathered on the end of the pipe m, the latter is put into place through the parts e and b5, the end of the pipe projecting through the rubber packing b', thus making it airtight,and on into the chamber m', until the collar m2 is just inside of or through et, and then the clamp J J' is securely closed, tightly gripping the pipe m. This body of glass is then put onto the block B4, where it goes through the preliminary forming process, well understood by glass-blowers who work it by hand. To do this part of the work, thc

glass ball has to be turned or rolled around and around or from side to side. This I can do by my blowing-machine. The operator does this by turning t-he Wheel C". the handle, es he turns the wheel C., thus operating the shaft c5 through the medium of the pinion-wheel c6. This turns the small bevelwheel c4, and as this works inthe large wheel C the motion aforesaid is given to the glass,a nd here the operator can turn his glass at will. As an equivalent for the wheel Gthe crank C may be used on the end of the shaft c5, irst removing the pinionwheel e and the set-screw el. Through this movement the glass can be turned at will during the entire blowing process, in the same manner or to the same effect as a glass-blower can do it by the old way. The actual blowing is done by means of the compressed air being admitted to the chamber m' from the valve (c2) chamber. Then it is desired to admit air to the glass ball to "blow7 it, the valve e2 is pushed inward, the pressureA Taking hold of 7o lating the handle fl, as before stated. Thus little or much air can be admitted at will. )Vhile this blowing is going on, the glass cylinder L has to be swung to and fro, as is done by hand-blowing. Such a movement I accomplish by turning the parts A3 and A' on their axis, thus revolving the other sections A2,and A,into and out of the pit l?. This revolving can bc done again and again,as long or as frapidly as may be needed, till the cylinder of glass has been fully formed. During this process of blowing it will be necessary to reheat the ball or cylinder L, and this I provide for by placing my turn-table H on a carriage, H', to run on a track, H2 H2. By this means I can run the glass ball or cylinder L into the blowfurnaceB', as will readily be seen by reference to Fig. 5, and when the cylinder is properly heated the carriage is reversed or run back. Vhen fully blown,the cylinder is laid on the rack B2.

Having thus described my invention, what `I claim, and desire to secure by Letters Patent, is

l. The carriage H', having thereon the turntable H, revolving on wheels, substantially as described, and for the purpose set forth.
